On the old RPi3 HASS.io installation, I had a section called homeassistant: which contained the customize: setting.
On the new HASS.io installation on the Ubutntu server under Docker, that section does not exist. So, if I try to use the Customize feature in the Configuration section of the UI, I get the red error
'It seems that your configuration.yaml doesnt properly include customize.yaml
Changes made here wont affect your configuration.'
Should this section be a part of HASS.io given the nature of the new onboarding process?
